SIMON J. FREEMAN, OF NEW YORK, N. Y., ASSIGNOR TO MARY FREEMAN, OF SAME PLACE.

FASTENER FOR MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent 1\T0.'229,995, dated July 13, 1880.

Application filed May 19, 1880.

To all whom it may concern:

Be it known that I, SIMON J. FREEMAN, of the city, county, and State of New York, have invented a new and useful lmprovement in Fasteners for the Meeting-Rails of Sashes,(Gase 13,) of which the following is a specification.

Figure 1 is a sectional side elevation of the improvement. Fig. 2 represents the lower side of the rear part of the lock, the cap-plate be- IO ing removed. Fig. 3 represents the lower side of the forward part of the lock, the cap-plate being removed.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish window-sash looks so constructed as to fasten the sashes automatically as the sash is closed, which cannot be unfastened from the outer side of the window, and which shall be simple in construction, strong, durable, and not liable to get out of order.

The invention consists in constructing a sash-lock of two boxes, a sliding hook having a orosshead upon its shank, a hinged hook 2 5 having a projection, springs for holding the hooks, and a' sliding block and its rod for disengaging the hooks, whereby the lock will fasten itself as the sash is lowered, and cannot be unfastened from outside the window, as will be hereinafter fully described.

A represents the casing, B the upper sash, and O the lower sash, of a window.

D is a box made with an open bottom, slotted forward side, and flanges upon its ends to receive the screws by means of which the said box I) is secured to the bottom rail of upper sash, B. The open bottom of the box D is closed by a cap-plate, E, secured in place by screws.

F is a hook which is placed in the slot in the forward side of the box D, and which has a cross-head formed upon the end of its shank. The ends of the cross-head of the hook F rest against shoulders formed in the end parts of the box D, so that the said hook cannot rise. The ends of the cross-head of the hook F are perforated to receive the guide-rods G, the ends of which are attached to the front and rear sides of the box D. The rods G serve as guides to the hook F as it moves in and out,

(Model.)

and also serve to prevent the said hook from rising. The hook F is held forward by spiral springs H, placed upon the rear parts of the guide-rods G.

I is a box made with an open bottom, a slotted rear side, and flanges upon its ends to receive the screws by means which the said box I is fastened to the top rail of the lower sash, O. The open bottom of the box Iis closed by a cap-plate, J, secured to the said box I by screws.

K is a hook which is placed with its shoulder downward to engage with the shoulder of the hook F when the said hook F is projected into the box I. The end of the shank of the hook K is hinged in the upper forward part of the box I by a pin passing through it or a cross-head formed upon it, the ends of which rest against shoulders formed in the said box I. The hook K is made of such a length that its hooked end may be flush with the rear side of the box I. The hooked end of the hook K is held down by a spring, L, interposed between it and the top of the box I. The outer ends of the hooks F K are beveled or rounded off, so that when the sash C is lowered into place the inclined rear side of the top rail of the lower sash, C, may push the hook F back into the box D. As the hook F passes the top rail of the lower sash, G, the springs H force it forward to enter the box I, so that the hook K will interlock with it, as shown in Fig.1, fastening the sashes.

The part of the inclined outer side of the top rail of the lower sash, 0, against which the end of the hook F strikes is faced with a metal plate to prevent it from being worn, which metal plate may be a flange formed upon the cap-plate J, or a separate plate, as may be desired or convenient.

Upon the lower side of the middle part of the hook K is formed an inclined projection, M, for the inclined upper side of the block N to strike against to raise the hook K away from the hook F. The block N slides in the cavity of the box I, and is moved by a rod, 0, which passes in through a hole in the forward side of the box I, and has a knob upon itsjouter end for convenience in operating it.

With this construction, when the sashis to be 10c unfastened, the rod 0 is pushed inward, which forces the block N against the projection M and raises the hook K away from the hook F. As the block N continues to advance its end strikes against the end of the hook F and forces the said hook F back into the box D, allowing the sash O to be raised. As the sash (J is lowered and the end of the hook F comes opposite the end of the block N the springs H force the said hook F forward, forcing the block N into the forward part of the boX I, allowing the hook K to engage with the hook F,looking the sash, so that the look will fasten itself as the sash O is lowered into place.

Having thus described my invention, I claim as new and'desire to secure by Letters Patent- SIMON J. FREEMAN.
